To all whom it' may concern.'

Be it known that I, TIMOTHY C. MAN- NING, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Grain- Door Removers, of which the following is a specification.

This invention relates to a grain door remover, and has for its object to provide an implement consisting of few and simple parts which may be economically manufactured and which will be convenient in use for removing the boards, plank or other strip-sections from the posts of the doorway of a grain car readily and in such a manner that splitting or injury of the lumber may be avoided.

It is well known that large quantities of lumber are wasted in shipping grain on railway cars, the plank or board strips employed and which are nailed to the inner sides of the door posts as a substitute for doors, generally being cut, split or otherwise injured in order that the grain may be removed, and since the lumber used must be of good quality, the financial loss, each year, is very great. The invention includes a fulcrum-plate for engaging a door-jamb and a lever so arranged that the boards may be pressed inwardly against the force or outward pressure of the grain, and may be detaclied from the posts or door-jambs without injury.

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illust-rated in the accompanying drawing, wherein,-

Figure 1 is a transverse section through a part of a grain car showing a side view of the device, the position of parts showing the lever before it has been moved for removal of a board or section. Fig. 2 is a similar view to that shown in Fig. 1, showr ing the position of the lever after it has been swung downwardly for detaching a board or section. Fig. 3 shows an end view of the fulcrum-plate. Fig. 4f is a side view of the same. Fig. 5 is a plan view of the doorway, the door-jambs being in section, the position of parts being the same as shown in Fig. 1. Fig. 6 is a side view of the lever.

The invention is illustrated in connection with a grain car 7, the pair of door-jams for the doorway 8 being indicated at 9. At 10 are indicated board or plank strips disposed edge to edge upon the inner side of the door-jambs, these being secured to the jambs, according' to custom, by nails a, as a substitute for a door, before the grain is deposited in the car; and before unloading the car, a removal of the strips 10 is necessary.

n order that the boards may be removed without material injury I provide a ful Crum-plate 11 having a wing 12 preferably provided at its terminal with transversely projecting teeth 13, the wing 12 being dis posed substantially at right angles to the plate so 'that it may engage that sideof a door-j amb above the upper edge of the uppermost board or strip 10, with the plate 11 disposed adjacent to said door-j amb, as best shown in Fig. 5.

The plate 11 is preferably of elongated form so that its lower end may be provided with a contact-finger or spacing-member 14, somewhat remote from the wing 12; and projecting from the same side of the plate, midway between the wing and nger 14, is a second contact-finger or spacing-member 15, being a part of a stationary pivot-pin 16 which projects outwardly from the opposite side of the plate.

At 17 is indicated a hand-lever or operating-bar, mounted between its ends upon the pin 16, said lever preferably being pro* vided at its end with a toothed swivel or rack-bar 18, its pivotal mounting being indicated at 19. Numeral `20 indicates a slot which is formed longitudinally in the lever adjacent to its rack and having recesses opening on the slot at intervals, as indicated at b, c and cl. l

By use of the device thus described, the strips 10 may be quickly detached from the door-joists. In operation, the device is first disposed as shown in Fig. l, its upper end engaging the inner side of the door-jamie above the strips 10, the rack engaging the outer side of the uppermost strip, and by moving the lever in a limited circles arc the strip may be readily moved inwardly of the car without injury, regardless of the pressure of the grain or resistance occasioned by the nails. After the uppermost strip has been detached, the plate 11, which provides the fulcrum for the lever, is moved downwardly on the post to permit the rackl may change minor details, and may change form and size of parts and also their proportions as may be found to be of advantage since it is the invention as claimed that determines its scope.

The use ofthe slot is a feature of advantage since the weight of the grain will tend to press a strip 10 outwardly against the dcor-jambs after the strip has been detached, and on account of the provision of the slot, the lever may be moved longitudinally, independently of the plate 11, for detaching the rack-bar from the strip, after the latter has been detached.

Also, since some of the nails employed may have an extreme length, the recesses l), c and d are of advantage so that the strips or sections 10 may be moved inwardly' of the car a distance corresponding to the length of the nails, the lever being disposed with the recess d receiving the pin 16 if the nails are of considerable length, the center of the arc of movement for the rack-bar being the pivotpin 16.

By use of the fingers or spacing-me1nbers i 14E and 15, any lateral swinging movement of the plate 11 will generally be prevented. They are of advantage on account of the uneven surfaces, pockets or depressions which are generally formed in door-jambs of grain cars, incident to their use; and by use of two members 14 and 15, the plate 11 may be maintained at right angles to the boards or sections 10; also the hand-lever may swing freely without engaging the housing-strip e which is secured to the doorframe and which often projects inwardly of the doorway.

It is obvious that the device would be operative if the toothed member 18 was dispensed with, but it is preferred since the stresses are directed to a greater area, which tends to prevent injury to the strips or board-sections. Also, if the slot 2U was omitted, operation in removing the strips would not be prevented, but by use of the construction substantially as shown, operation is convenient and eiective, and these features do not add materially to the cost of manufacture.

What l claim as my invention is,-

l. A grain door remover comprising a ful- Crum-plate having a toothed wing and a spacing finger projecting outwardly from one of its sides, its opposite side being pro* vided with a pivot-pin, a lever provided near one of its ends with a slot for receiving the pivot-pin and having a toothed member pivotally mounted thereon at its end, adjacent to said slot. j

2. A grain door remover comprising a fulcrum-plate having a wing projecting outwardly from one of its sides, its opposite side being provided with a pivot-pin, a lever having a slot formed longitudinally therein and having recesses opening 0n the slot, said lever being adapted to be mounted with `its Slot and one of said recesses receiving said pivot-pin, a toothed member pivotally mounted upon the lever adjacent to said slot, the terminal part of said wing being provided with projections.

ln testimony whereof I have affixed my y signature in presence of two witnesses.
